Aprašymas

Research Paper (postgraduate) from the year 2018 in the subject Agrarian Studies, grade: Degree of MASTER, Jimma University College of Agriculture and Veterinary Medicine (Jimma University), course: Horticulture, language: English, abstract: Haphazard and inappropriate plant spacing and poor soil fertility management practices are among the major factors constraining onion production in the Central Zone of Tigray. Therefore, a field experiment was conducted in Axum district from October to March 2014 to assess the influence of intra-row spacing (2.5, 5, 7.5, 10 and 12.5 cm) and nitrogen rate (0, 41, 82 and 123 kg N ha-1) on growth, bulb yield, and quality of onion. The experiment was laid out in a randomized complete block design (RCBD) of factorial arrangement with three replications. The main effects of nitrogen rate and intra-row spacing influenced only the plant height and stand count significantly (P
